NR 507 FINAL EXAM 2 – QUESTION AND
ANSWERS
Question 1
pts
Tissue damage caused by the deposition of circulating immune
complexes containing an antibody against the host DNA is the cause of
which disease?
Hemolytic anemia
Pernicious anemia
Systemic lupus erythematosus
Myasthenia gravis
Only the deposition of circulating immune complexes containing an
antibody against the host DNA produce tissue damage in individuals
with systemic lupus erythematosus (SLE).
Question 2
pts
How does chest wall compliance in an infant differ from that of an
adult?
An adult’s chest wall compliance is lower than an infant’s.
An adult’s chest wall compliance is higher than an infant’s.
An adult’s chest wall compliance is the same as an infant’s.
An adult’s chest wall compliance is dissimilar to that of an infant’s.
,Chest wall compliance is higher in infants than it is in adults,
particularly in premature infants.
Question 3
pts
What term is used to describe a hernial protrusion of a saclike cyst that
contains meninges, spinal fluid, and a portion of the spinal cord
through a defect in a posterior arch of a vertebra?
Encephalocele
Meningocele
Spina bifida occulta
Myelomeningocele
Myelomeningocele is a hernial protrusion of a saclike cyst containing
meninges, spinal fluid, and a portion of the spinal cord with its nerves
through a defect in the posterior arch of a vertebra. The remaining
options are not appropriate terms to identity the described condition.
Question 4
pts
Continued therapy of pernicious anemia (PA) generally lasts how long?
6 to 8 weeks
8 to 12 months
Until the iron level is normal
The rest of one’s life
,Because PA cannot be cured, maintenance therapy is a life-long
endeavor.
Question 5
pts
Cytokines are thought to cause fevers by stimulating the synthesis of
which chemical mediator?
Leukotriene
Histamine
Prostaglandin
Bradykinin
Cytokines seem to raise the thermoregulatory set point through
stimulation of prostaglandin synthesis and turnover in
thermoregulatory (brain) and nonthermoregulatory (peripheral)
tissues. The other options do not accurately identify the appropriate
chemical mediator.
Question 6
pts
The World Health Organization (WHO) defines grade 1 (overweight) as
a BMI of:
18.5 to 24.9
25 to 29.9
30 to 39.9
40 to 50.9
, A BMI of 25 to 29.9 kg/m2 is considered a grade 1 (overweight)
classification. A BMI of 18.5 to 24.9 kg/m2 is considered normal range,
whereas 30 to 39.9 kg/m2 is a grade 2 (severe overweight)
classification, and a BMI higher than 40 kg/m2 is considered grade 3
(morbidly overweight).
IncorrectQuestion 7
pts
When diagnosed with hemolytic disease of the newborn (HDN), why
does the newborn develop hyperbilirubinemia after birth but not in
utero?
Excretion of unconjugated bilirubin through the placenta into the
mother’s circulation is no longer possible.
Hemoglobin does not break down into bilirubin in the intrauterine
environment.
The liver of the fetus is too immature to conjugate bilirubin from a
lipid-soluble to water-soluble form.
The destruction of erythrocytes producing bilirubin is greater after
birth.
Hyperbilirubinemia occurs in the neonate after birth because excretion
of lipid-soluble unconjugated bilirubin through the placenta is no
longer possible. This selection is the only option that accurately
explains why HDN causes hyperbilirubinemia after birth but not in
utero.
Question 8
pts
Which of the following describes how the body compensates for
anemia?
Increasing rate and depth of breathing
Decreasing capillary vasoconstriction
Hemoglobin holding more firmly onto oxygen
